Planes of the Libyan Air Force reportedly opened fire on protesters in central Tripoli. There is no way to confirm this currently, but we are getting many reports of chaos on the streets of the capital.

"Further reports of live ammunition being used on protesters in Tripoli, with lots of tweets saying security forces are again driving cars around the city, shooting at everyone and everything," Al Jazeera reported.

Ahmed Elgazir, a human rights researcher, told Al Jazeera that Libya News Center, an organization based in Geneva, had received a call for help from a woman "witnessing the massacre" in progress who called on a satellite phone after land lines were cut.
